IMPROVEMENT IN ROTARY ENGINES.

Specification forming part of Letters Patent No. 176,878, dated May 2,1876; application led February 28, 1876.

To all whom it may concern Be it known that I, J osEPHUs MooEE, o MoundValley, in the county of Labette and State of Kansas, have invented anew and Improved Rotary Engine, of which the following is aspecification This invention consists of avpair of cylinders. withpistons set opposite, eachother for one to take steam when the other isnot taking it, with abutments which slide out and in to let the pistonspass, and are worked by cam-disks outside of the cylinders; also withtwo sets of slide-valves for running theengine either way, the valvesbeing workedby eccentrics on the shaft outside of the cai e, and alsowith two sets of exhaust-ports for use according tothe way the engineruns, the valves of which are connected to the reversing-valves, so asto shift simultaneously with them.

The steamways are constructed in the form of a round ring, and thepistons are in the form of a segment of a ring, and are attached to theedge lof a disk keyed on the shaft, so as to be fitted with ordinaryround pistonpacking.

Figure l is a sectional elevation of my improved engine, taken on theline a; .fr ot' Fig. 2. Fig. 2 is a sectional elevation taken on line yy of Fig. l. Fig. 3 is a side elevation.

Fig. 4 Ls a top view, and Fig. 5 is an elevation of the piston. Y

Similar letters of reference indicate corresponding parts. v

A represents the steamways arranged side by side around the shaft B, onwhich are the disks C, each having a piston, D, on its periphery,running in one of the steamways. E represents the slidin g' abutments,which are worked by the grooved cams F and bars Gr, one being raisedwhen the other is down. H and I are two inlet-ports to each cylinder,

ports I, of both engines, said valves beingl Worked by thev eccentrics Nand rods O. P is a reversing-valve, and R S exhaust-valves,

both of the latter being connected to the lever' 'l of thereversing-valve, so that when steam is admitted at H to run the engineto the left the exhaust-port J will b e closed by valve R, and port Kwill be opened, and when admitted atl, to run to the right, portK willbe closed and J opened.

' The round form oi' the piston is represented in Fig. 5, showing theconnection ot' it to the disk by the center stud U and bracket W. Thisform enables it .to be packed all round, the same as the piston otAreciprocating engines, or better than the angular form commonly used inrotary engines. The steam may be Worked expansively in this contrivanceby setting the eccentrics to cut o" in advance of the exhaust, or, inother words, before the pistons arrive at the exhaust-ports.

Having thus described my invention, I claim as new and desire to secureby Letters Patcnt- 1. rlhe combination, in a rotary stcal'n-engine, ofthe two parallel steam-chambers A,
